Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a waste gas purification device for agricultural machinery manufacturing. Background Technique

[0002] Agricultural machinery, also known as farm machinery, refers to various machinery used in the processes of crop planting and animal husbandry production, as well as in the primary processing and treatment of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farm construction machinery, soil tillage machinery, planting and fertilizing machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery, and agricultural transportation machinery, etc. However, during the casting production process of some agricultural machinery, a large amount of harmful gases containing metal oxides, dust, etc. will be generated, seriously affecting the surrounding environment and human health. In order to remove the harmful substances in the waste gas, make the waste gas meet the emission standards, and protect human health, a waste gas purification device is needed.

[0003] For example, a waste gas purification device with the publication number 202320348233.5 includes an air vent pipe. An intake pipe is installed at the bottom of the air vent pipe, an exhaust pipe is installed at the top of the air vent pipe, a purification box is installed in the middle of the air vent pipe. A chute is opened on the inner side wall of the purification box, a sliding rod is slidably connected inside the chute, an activated carbon filter screen is installed on one side of the sliding rod, and the activated carbon filter screen is hermetically slidable in the middle of the air vent pipe. A lead screw is installed on one side of the activated carbon filter screen, and a cleaning block is installed inside the purification box.

[0004] The above device can clean the activated carbon filter screen by installing structures such as a cleaning block and a lead screw inside the purification box, prevent it from being blocked, and extend the service life of the activated carbon filter screen. When in use, the gas enters the inside of the purification box from the intake pipe and is filtered through the activated carbon filter screen. After long-term use, the activated carbon filter screen will be covered with dust particles adsorbed from the waste gas. By rotating the lead screw, the activated carbon filter screen is driven to move. During the movement, the cleaning block cleans the activated carbon filter screen. By rotating the lead screw, the activated carbon filter screen inside the air vent pipe is replaced to improve the filtering effect. However, this device can only purify the waste gas singly by the activated carbon filter screen, resulting in a small amount of harmful substances still remaining in the purified waste gas. Secondly, due to the high temperature of the waste gas and the lack of a cooling mechanism in the purification device itself, when the waste gas containing a small amount of harmful substances and high temperature is discharged into the air, it will still cause environmental pollution, greatly reducing the purification effect of the waste gas. Therefore, we provide a waste gas purification device for agricultural machinery manufacturing. Content of the Utility Model

[0005] The content of this application is used to briefly introduce concepts, which will be described in detail in the specific implementation section later. The content section of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0006] The purpose of the present utility model is to provide an exhaust gas purification device for agricultural machinery manufacturing to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: An exhaust gas purification device for agricultural machinery manufacturing, including a support plate. On the left side of the top of the support plate, a fan is fixedly installed, and the input end of the fan is connected to an intake pipe. The output end of the fan is connected to a first guide pipe, and one end of the first guide pipe is connected to a first purification box. At the top of the inner cavity of the first purification box, a UV photolysis tube is fixedly installed, and at the bottom of the inner cavity of the first purification box, a group of titanium dioxide catalyst plates are arranged.

[0008] Further, the right side of the first purification box is connected to a second guide pipe, and one end of the third guide pipe is connected to a second purification box. At the top of the second purification box, a water pump is fixedly installed, and the input end of the water pump is connected to a water inlet pipe. The output end at the bottom of the water pump is connected to a water guide pipe, and one end of the water guide pipe penetrates to the top of the inner cavity of the second purification box and is connected to a water storage pipe. At the bottom of the water storage pipe, a group of atomizing nozzles are arranged.

[0009] Further, the right side of the second purification box is connected to a third guide pipe, and one end of the third guide pipe is connected to a third purification box. Inside the third purification box, a group of activated carbon filter cotton plates are arranged, and the top of the third purification box is connected to an exhaust pipe.

[0010] Further, a flow guide plate is arranged at the bottom of the inner cavity of the second purification box, and the right side of the bottom of the second purification box penetrates to the bottom of the support plate and is connected to a drain pipe. At the bottom of both sides of the inner cavity of the second purification box and above the flow guide plate, filter mesh plates are arranged.

[0011] Further, the bottom of the support plate is fixedly connected to support columns, and the bottom of the support columns is fixedly connected to rubber pads.

[0012] Further, the fronts of the first purification box, the second purification box, and the third purification box are threadedly connected with cover plates, and bolts are threadedly connected around the cover plates.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The utility model sucks harmful gases containing metal oxides, dust, etc. generated during the manufacture of external agricultural machinery through a fan in cooperation with an intake pipe, and discharges the waste gas into the inner cavity of a first purification box through a first guide pipe. Through the cooperation of a UV photolysis tube and a titanium dioxide catalyst plate, organic pollutants and other harmful substances in the waste gas can be effectively degraded and removed. The principle is that ultraviolet rays within a specific wavelength range can activate oxygen molecules in the waste gas, generating highly reactive oxygen free radicals and ozone. These active oxygen species have strong oxidation ability and can chemically react with harmful substances in the waste gas, decomposing them into harmless substances, and preliminarily filtering the waste gas to achieve the purpose of primary purification of the waste gas.

[0015] 2. The waste gas preliminarily filtered by the first purification box of the utility model is discharged into the inner cavity of the second purification box through a second guide pipe. At the same time, water from the outside is sucked through a water pump in cooperation with an intake pipe, and then the water is transported to the inner cavity of a water storage pipe through a water guide pipe, and the water is atomized through an atomizing nozzle and continuously sprayed into the inner cavity of the second purification box to form a water mist. When the waste gas entering the inner cavity of the second purification box comes into contact with the water mist, the water mist can cause the particulate matter in the waste gas to agglomerate or settle, achieving the purpose of filtration and cooling, and thus achieving the purpose of secondary purification of the waste gas.

[0016] 3. The waste gas secondary purified by the first purification box of the utility model is discharged into the inner cavity of the second purification box through a third guide pipe. Through the setting of an activated carbon filter cotton board, the waste gas is purified again. Since the activated carbon filter cotton board uses an aluminum honeycomb with a through-hole structure as a carrier, harmful substances in the waste gas can be adsorbed again, and through the setting of an exhaust pipe, the gas purified at multiple levels is discharged, thus achieving the purpose of tertiary purification of the waste gas.

[0026] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] The present utility model provides an exhaust gas purification device for agricultural machinery manufacturing as shown in Figures 1-4 Figure 1, which includes a support plate 1. A blower 2 is fixedly installed on the left side of the top of the support plate 1. The input end of the blower 2 is communicated with an air inlet pipe 3. The output end of the blower 2 is communicated with a first air guide pipe. One end of the first air guide pipe is communicated with a first purification box 4. A UV photocatalytic tube 9 is fixedly installed on the top of the inner cavity of the first purification box 4. And a group of titanium dioxide catalyst plates 10 are arranged at the bottom of the inner cavity of the first purification box 4.

[0028] The blower 2, in cooperation with the air inlet pipe 3, sucks in the harmful gases containing metal oxides, dust, etc. generated during the manufacturing of external agricultural machinery, and discharges the exhaust gas into the inner cavity of the first purification box 4 through the first air guide pipe. Through the cooperation of the UV photocatalytic tube 9 and the titanium dioxide catalyst plates 10, the organic pollutants and other harmful substances in the exhaust gas can be effectively degraded and removed. The principle is that ultraviolet light within a specific wavelength range can activate the oxygen molecules in the exhaust gas to generate highly reactive oxygen free radicals and ozone. These active oxygen species have strong oxidation ability and can react chemically with the harmful substances in the exhaust gas to decompose them into harmless substances, preliminarily filtering the exhaust gas, so as to achieve the purpose of primary purification of the exhaust gas.

[0029] SeeFigure 1 and Figure 3 As shown in Figure 3 , a second air duct is connected to the right side of the first purification box 4, and one end of the third air duct is connected to the second purification box 5. A water pump 6 is fixedly installed on the top of the second purification box 5, and a water inlet pipe is connected to the input end of the water pump 6. The output end at the bottom of the water pump 6 is connected to a water guide pipe, and one end of the water guide pipe penetrates through the top of the inner cavity of the second purification box 5 and is connected to a water storage pipe 11. A group of atomizing nozzles 12 are arranged at the bottom of the water storage pipe 11.

[0030] The waste gas preliminarily filtered by the first purification box 4 is discharged into the inner cavity of the second purification box 5 through the second air duct. At the same time, the water pump 6 sucks in external water in cooperation with the water inlet pipe, then conveys the water to the inner cavity of the water storage pipe 11 through the water guide pipe, and continuously sprays the water into the inner cavity of the second purification box 5 after atomizing the water through the atomizing nozzles 12, so as to form a water mist. When the waste gas entering the inner cavity of the second purification box 5 contacts the water mist, the water mist can cause the particulate matter in the waste gas to agglomerate or settle, achieving the purpose of filtration and cooling, and thus achieving the purpose of secondary purification of the waste gas.

[0031] See Figure 1 and Figure 4 As shown in Figure 4 , a third air duct is connected to the right side of the second purification box 5, and one end of the third air duct is connected to the third purification box 7. A group of activated carbon filter cotton plates 14 are arranged in the inner cavity of the third purification box 7, and an exhaust pipe 8 is connected to the top of the third purification box 7.

[0032] The waste gas secondary purified by the first purification box 4 is discharged into the inner cavity of the second purification box 5 through the third air duct. Through the arrangement of the activated carbon filter cotton plate 14, the waste gas is purified again. Since the activated carbon filter cotton plate 14 uses an aluminum honeycomb with a through-hole structure as a carrier, it can adsorb harmful substances in the waste gas again, and through the arrangement of the exhaust pipe 8, the gas after multi-stage purification is discharged, thus achieving the purpose of tertiary purification of the waste gas.

[0033] See Figure 1 and Figure 3 As shown in Figure 3 , a flow guide plate is arranged at the bottom of the inner cavity of the second purification box 5, and a drain pipe 15 is connected to the right side of the bottom of the second purification box 5 and penetrates through the bottom of the support plate 1. Filter mesh plates 13 are arranged at the bottom of both sides of the inner cavity of the second purification box 5 and above the flow guide plate.

[0034] The particulate matter generated after the water mist purifies the waste gas is filtered through the filter mesh plates 13 to prevent the filtered particulate matter from being discharged to the outside following the water flow, thereby causing environmental pollution. Since the top of the flow guide plate is inclined, and in cooperation with the drain pipe 15, the purpose of accelerating drainage is achieved.

[0035] See Figure 1 As shown in Figure 1 , support columns are fixedly connected to the bottom of the support plate 1, and rubber pads are fixedly connected to the bottoms of the support columns.

[0036] Through the setting of the support columns, the purpose of the support device can be achieved. Through the setting of the rubber pads, the vibration during the operation of the device can be reduced, thereby improving the stability of the device during operation.

[0037] See Figure 1 As shown, the front sides of the first purification box 4, the second purification box 5 and the third purification box 7 are threadedly connected with cover plates, and bolts are threadedly connected around the cover plates.

[0038] By unscrewing the bolts to remove the cover plates, the accessories inside the several purification boxes can be regularly inspected, maintained and replaced, thereby improving the use effect and service life of the device.

[0039] In summary, when the waste gas purification device for agricultural machinery manufacturing is in use, first, the fan 2 inhales the harmful gas containing metal oxides, dust, etc. generated during the external agricultural machinery manufacturing in cooperation with the intake pipe 3, and discharges the waste gas into the inner cavity of the first purification box 4 through the first air duct. Through the cooperation of the UV photolysis tube 9 and the titanium dioxide catalyst plate 10, the organic pollutants and other harmful substances in the waste gas can be effectively degraded and removed, and the waste gas is preliminarily filtered. The waste gas preliminarily filtered by the first purification box 4 is discharged into the inner cavity of the second purification box 5 through the second air duct. At the same time, the water pump 6 inhales the external water in cooperation with the water inlet pipe, then conveys the water to the inner cavity of the water storage pipe 11 through the water delivery pipe, and sprays the water atomized through the atomizing nozzle 12 continuously into the inner cavity of the second purification box 5 to form a water mist. When the waste gas entering the inner cavity of the second purification box 5 comes into contact with the water mist, the water mist can cause the particulate matter in the waste gas to agglomerate or settle, achieving the purpose of filtration and cooling, thereby achieving the purpose of secondary purification of the waste gas. The particulate matter generated after the water mist purifies the waste gas is filtered through the filter mesh plate 13, and through the cooperation of the guide plate and the drain pipe 15, the purpose of accelerating drainage is achieved. The waste gas secondary purified by the first purification box 4 is discharged into the inner cavity of the second purification box 5 through the third air duct. Through the setting of the activated carbon filter cotton plate 14, the harmful substances in the waste gas are adsorbed again, and finally the purified gas is discharged through the exhaust pipe 8. Through the setting of the first purification box 4, the second purification box 5 and the third purification box 7, the purpose of multi-stage filtration of the waste gas is achieved, and the purification effect of the waste gas is greatly improved.

[0040] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
